The Agile Release Train (ART) supports Release on Demand by ensuring that new functionality can be released to the end users at a moment's notice, which is a critical aspect of the Continuous Delivery Pipeline.
This is achieved through two key practices:
* Decouple deployment from release : This practice allows for the deployment of new functionality into production without making it immediately visible to end users. It provides the flexibility to release features incrementally based on business needs, rather than being tied to the deployment schedule1.
* Continuous Integration (E): Continuous Integration is a software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run. The key benefits of Continuous Integration include the ability to detect and fix integration issues early, leading to more reliable software and faster development cycles. This practice is fundamental to supporting Release on Demand because it ensures that the software is always in a releasable state, which is essential for the quick release of new features1.
These practices are part of the larger framework of SAFe, which emphasizes the importance of ARTs being able to deliver value efficiently and effectively to meet customer and business needs.
